Barrier gate

Abstract

The invention discloses a barrier gate which comprises a speed reducer, a brake bar, a motor and a mounting seat, wherein the speed reducer is arranged on the mounting seat, the input end of the speedreducer is connected with the output end of the motor, the speed reducer is provided with a cavity for mounting of the output shaft of the speed reducer; one end, located in the cavity, of the outputshaft is fixedly connected with a rear axle cover of the speed reducer; and one end, located outside the cavity, of the output shaft is fixedly connected with the brake bar by a slot. According to the invention, the output shaft of the speed reducer is arranged in the cavity of the speed reducer, and two ends of the output shaft are respectively fixedly connected with the brake bar and the rear axle cover of the speed reducer, that is, the output shaft of the speed reducer is used as a main shaft of the barrier gate, and therefore, secondary connection of the output shaft and the main shaft is avoided, and further self-rotation error is avoided, and abrasion of the output shaft to internal parts of the speed reducer is reduced.

Description

technical field [0001] The invention relates to the field of road equipment, in particular to a barrier gate. Background technique [0002] Barrier gate is a channel entrance and exit management equipment specially used to restrict motor vehicles on the road. It is generally composed of reducer, motor, transmission mechanism, bearing seat, chassis, brake lever and other parts. In the prior art, the main shaft of the barrier gate connected to the gate lever and the output shaft of the reducer are connected through a linkage mechanism. This structure has complicated installation procedures and requires very high coaxiality between the two shafts. Moreover, this secondary connection structure may cause an autopropagation error when the main shaft and the output shaft are connected and transmitted, affecting the normal operation of the barrier gate. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to s...
